Class InstanceAdmin (2.16.0)

Implements the APIs to administer Cloud Bigtable instances.

Thread-safety

Instances of this class created via copy-construction or copy-assignment share the underlying pool of connections. Access to these copies via multiple threads is guaranteed to work. Two threads operating concurrently on the same instance of this class is not guaranteed to work.

Cost

Creating a new object of type InstanceAdmin is comparable to creating a few objects of type std::string or a few objects of type std::shared_ptr<int>. The class represents a shallow handle to a remote object.

Error Handling

This class uses StatusOr<T> to report errors. When an operation fails to perform its work the returned StatusOr<T> contains the error details. If the ok() member function in the StatusOr<T> returns true then it contains the expected result. Operations that do not return a value simply return a google::cloud::Status indicating success or the details of the error Please consult the StatusOr<T> documentation for more details.```cpp namespace cbt = google:☁️:bigtable; namespace btadmin = google::bigtable::admin::v2; cbt::InstanceAdmin admin = ...; google:☁️:StatusOr<btadmin::Instance> instance = admin.GetInstance(...);

if (!instance) { std::cerr << "Error fetching instance\n"; return; }

// Use instance as a smart pointer here, e.g.: std::cout << "The full instance name is " << instance->name() << "\n";


In addition, the [main page](xref:index) contains examples using [`StatusOr`](xref:classgoogle_1_1cloud_1_1StatusOr)`<T>` to handle errors.



###### Retry, Backoff, and Idempotency Policies

The library automatically retries requests that fail with transient errors, and uses [truncated exponential backoff](https://cloud.google.com/storage/docs/exponential-backoff) to backoff between retries. The default policies are to continue retrying for up to 10 minutes. On each transient failure the backoff period is doubled, starting with an initial backoff of 100 milliseconds. The backoff period growth is truncated at 60 seconds. The default idempotency policy is to only retry idempotent operations. Note that most operations that change state are **not** idempotent.
The application can override these policies when constructing objects of this class. The documentation for the constructors show examples of this in action.

Returns

Type Description

future< StatusOr< google::bigtable::admin::v2::Instance > >

a future that becomes satisfied when (a) the operation has completed successfully, in which case it returns a proto with the Instance details, (b) the operation has failed, in which case the future contains an exception (typically bigtable::GrpcError) with the details of the failure, or (c) the state of the operation is unknown after the time allocated by the retry policies has expired, in which case the future contains an exception of type bigtable::PollTimeout.

ListInstances()

Obtain the list of instances in the project.

Note: In some circumstances Cloud Bigtable may be unable to obtain the full list of instances, typically because some transient failure has made specific zones unavailable. In this cases the service returns a separate list of failed_locations that represent the unavailable zones. Applications may want to retry the operation after the transient conditions have cleared.

This operation is read-only and therefore it is always idempotent.
